Cold Places: pictures from the Poles

"I took this shot on one of the coldest shoots I’ve ever experienced,
during filming for Planet Earth. It was -30°C at times - and they were
testing conditions for both people and camera gear. But I felt most sorry
for the eider ducks. They were diving in a polyna – a hole in the sea ice
kept open by strong currents – collecting urchins and mussels from the
seabed, their only source of food during the Arctic winter." Belcher Islands, Hudson Bay, Canada.
